Originally posted by vegenigma For the most part, yes. I'm beginning to think I just have standards that the K-x w/ kit lens doesn't live up to. With all the reviews I perused, I'm surprised I didn't read much about problems w/ sharpness deficiency at wide aperture.
Couple of things here -
1. Kit lenses are usually not good. Some people say that they are good value for money. But, personally, I never use the kit lens; my advice is to get the camera body only. Lenses make all the difference. A good lens is going to give you good pictures even on a 500$DSLR. But an average lens will give you average pictures even on 2000$ DSLR. If you are buying a DSLR and are thinking of using the kit lens for long, you won't be happy (if you have high standards).
2. Regarding the reviews, reviews will not elaborate on the type of lenses that were used. I usually read three main types of reviews. One - dxomark for sensor test. This is an excellent review site with a very scientific method of testing sensors. There is no subjective test. All accurate scientific data. This is the best site to see how the different camera sensors stack up.
b. For handling, body, features of the camera - I usually goto dprevw.
c. For lenses, I goto photozone.de. dxo mark also has lens tests but they have tested very few lenses so far.
To your original question, k-x is a really nice camera. If you check the sensor charts, it beats a lot of big names from Nikon and Canon. It even beats its bigger brother Pentax k-7 in many areas. K-x with a DA 40ltd, or DA 35 will be sufficiently sharp.
The things I don't like in k-x are - Autofocus, and viewfinder.
k-r will give you some more controls and a better AF. Image quality is the same as k-x (same sensor).
k-5 will give you the best possible APS-C sensor. Weather sealed body. And everything else. But it is outside your limit.
You can also look at Canon and Nikon. I don;t know the prices offhand, but there should be many good models available below 1000$.
If it were me (and I were not to get the k-5), I would get the k-x.
